Description
Technical field
The utility model relates to a kind of railway heavy rail motor car.
Background technology
The heavy rail motor car of domestic 290 horsepowers of grades has mechanical drive and hydraulic transmission dual mode at present.Mechanical drive mode: dispose power-transfer clutch, mechanical gear box etc., its operating system complexity, backward in technique, degree of automation is low, driver's labour intensity is big, can't realize the interlocking of whole-control system.Owing to be mechanical drive, starting has impact, and it is poor to adapt to load capacity automatically.The hydraulic transmission mode: hydraulic transmission rail vehicle gear is 2 grades, and speed range is narrow, and driving efficiency is low during high speed, is unsuitable for high-speed cruising.
Summary of the invention
The utility model is eliminated starting-impact in order to improve the starting ability of existing heavy rail motor car, makes starting be easy to control, steady; Change gear shift, variable speed operation mode; Control of improvement system and interlocking; Driving efficiency when improving high speed provides a kind of novel heavy duty rail vehicle.
The utility model adopts following technical scheme to realize: the novel heavy duty rail vehicle comprises the power drive system of establishing hydraulic mechanical transmission box.Power drive system is by forming with lower member: diesel engine, elastic coupling, hydraulic mechanical transmission box, commutation case, transmission shaft, axle gear box etc.Hydraulic mechanical transmission box is made up of the change-speed box of turbine transformer, tween drive shaft speed changing structure and the multiple disk clutch of fluid control, the hydraulic mechanical transmission box input end is and diesel engine bonded assembly turbine transformer that the hydraulic mechanical transmission box mouth is connected with axle gear box through the commutation case.Hydraulic mechanical transmission box is connected with electrohydraulic control system.Establish lockup clutch in the turbine transformer.
Diesel engine is for having world-class WD615 serial diesel engine, and this serial diesel engine has advantages such as volume is little, in light weight, power is big, oil consumption is low, discharge index is advanced, noise is low, highly versatile.The selected diesel engine of this power drive system is the construction machinery and equipment machine, has that reliability height, life-span length, good dynamic property, coefficient of torque reserve are big, good economy performance, advantages such as good altitude acclimatization ability, environmental protection is arranged.For the better requirement that adapts to the rolling stock tractive property, selected the full distance speed regulating injection pump for use, so that adapt to the traction speed adjusting performance better, had simultaneously good combustion performance again, the application of charge-air cooling system has improved combustion efficiency, makes its discharging reach Europe II effluent standard.
Hydraulic mechanical transmission box is made up of the change-speed box of turbine transformer, tween drive shaft speed changing structure and the multiple disk clutch of fluid control.Hydraulic mechanical transmission box has the characteristics of hydraulic transmission; as start steadily, starting tractive effort is big, can adapt to characteristics such as external load, control comfort automatically; be easy to realize automatic guidance; especially the exploitation of the interlock of power drive system and brake system; when having realized emergency braking; diesel engine returns idling automatically; make the return trip empty automatically the finishing of single stepping of shelves of change speed gear box; both guaranteed the parking promptly and accurately of vehicle; protect the equipment performance of power drive system again, had good Practical significance.Simultaneously, hydraulic mechanical transmission box has adopted six grades of mechanical speed changes, the compatible characteristics that the mechanical drive gear box is many, efficient is high, it is more reasonable to make that speed ratio distributes, when the speed of a motor vehicle reached certain setting value, the turbine transformer of change speed gear box can be realized the coupler lock function, and this moment, change speed gear box was the mechanical gear box of rigid attachment, driving efficiency improves greatly, makes power drive system have more superior performance condition.Tractive force increased when the dual nature of fluid power and machinery made hydraulic mechanical transmission box have the low speed starting, also can satisfy the needs of running at high speed simultaneously, made the locomotive full-throttle characteristics more near its idealized characteristic.
The hydraulic mechanical transmission box control system is an electrohydraulic control system, provides electric signal by driving switch, and the folding of hydraulic valve action control clutch realizes speed change.Gear controller is easier to operation, vision is directly perceived.Be equipped with the safety box device, locking reverse gear more than 3 grades, with the protection driving system.Owing to adopt turbine transformer, make change speed gear box 1,2 grade, when the speed of a motor vehicle is lower than 3km/h, can directly hangs and reverse gear, make the more simple and flexible that commutates.Compare with the mechanical drive rail vehicle, saved power-transfer clutch, operate more simple.
In order to guarantee the better performance of power transmission performance between diesel engine and change speed gear box, at the mouth of diesel engine elastic clutch is installed, make the resistance torsional oscillation of vehicle can very big influence not arranged to diesel engine.
Hydraulic mechanical transmission box designs for one-way traffic, therefore has been equipped with commutation operating mode case, has same tractive property when making the rail vehicle two way, and the conversion of direction is finished when the selection of driving position automatically.Commutation operating mode case two ends link to each other with former and later two axle gear boxs by transmission shaft respectively.One cover box of tricks is arranged on four of commutation auxiliary gear box, no matter the axletree rotating speed why reason produces in front and back is inconsistent, this diff all can play a role, and prevents or alleviate slide relative, the abrasion of reduction flange tread of wheel and rail.If in operational process, when running part et out of order after a certain mouth of commutation case or inefficacy, can become the twin shaft driving and drive on the diff lock into single shaft.When adopting this interim measure, the transmission shaft of at first should dismantling pushes away walking gear fork bar then inward, and after putting in place, walking gear combines with differential gear box, makes four to be become by two semiaxis and to be rigidly connected.
Axle gear box is a double reduction, and the first order is a Bevel Gear Drive, and the second stage is spur gear drive.Constitute by upper box, lower box, gear hub, finishing bevel gear cuter and cylindrical wheel, lubricating system.Because second stage cylinder big gear wheel hot charging on axletree, is not processed spline on axletree, improved the intensity of axletree.Axle gear box adopts the mode that pump fuel feed is lubricated and the gear lubrication by atomization combines, gear case by the torque arm resilient suspension on the bogie truck crossbeam.Facts have proved that the structure of this gear case is fit to the running under power characteristics of railroad track car very much, reliability is very high.
The utility model compared with prior art has following beneficial effect:
1, starting is steady, starting tractive effort is big, can adapt to external load automatically.
2, gearbox control system is an electrohydraulic control system, and easy operating, vision are directly perceived, commutation is arranged, move back a grade fender guard.
3, locomotive has been realized emergency braking interlocking and brake system low-voltage variation.
4, high speed district driving efficiency improves, and satisfies the requirement of locomotive high-speed cruising.
